[0002] In the production of biaxially oriented polyester film, the gravure roller in the online coating process plays a crucial role, controlling the transfer of coating liquid and ensuring uniform coating onto the substrate. The smooth surfaces at both ends of the gravure roller result in poor edge sealing, leading to leakage of coating liquid and subsequent drying at these locations. Furthermore, during production, the dried liquid at the edges of the gravure roller generates powder due to friction, which easily splashes onto the film surface and the doctor blade, causing white spots, streaks, and other defects on the film surface, thus affecting film quality.

[0003] Commonly used measures include adding a thick film to the smooth surface of the edges for shielding, or treating the dried liquid on the edges with a damp nonwoven fabric. These methods are labor-intensive and time-consuming, and because the gravure roller operates at continuous high speed, they pose a safety hazard to operators.

[0004] Therefore, it is necessary to improve the existing gravure roller edge removal device. Utility Model Content

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] like Figures 1-3As shown, the gravure roller edge wetting and cleaning device includes a base 1, a gravure roller 2, a coating head 3, a liquid inlet pipe 6, a wetting assembly 4, and a fine-tuning assembly 5. The base 1 has a bottom groove 10, and the gravure roller 2 and the coating head 3 are arranged above the bottom groove 10 and are in concave-convex fit. The liquid inlet pipe 6 is connected to the coating head 3. The wetting assembly 5 is located at both ends of the coating head 3 and connected to it, and has a liquid outlet 40 facing the gravure roller 2 and a cleaning component. The fine-tuning assembly 5 is used to adjust the wetting assembly 4 and the coating head 3 to be closer to or further away from the gravure roller 2. The liquid outlet 40 is connected to the liquid inlet pipe 6.

[0023] The rinsing assembly 4 has an outlet 40 and a cleaning component. The outlet 40 is connected to the liquid delivery pipe 6. By combining the principle of similar compatibility, the dry liquid is wetted and removed, which effectively solves the problem of dry liquid splashing on the edge of the gravure roller. The rinsing assembly 4 is connected to the coating head 3, which makes installation and setup simple. Furthermore, the fine-tuning assembly 5 can flexibly adjust the working and non-working states of the rinsing assembly 4, the coating head 3, and the gravure roller 2, which facilitates maintenance and replacement of parts.

[0024] To improve the wetting and cleaning effect of the dampening assembly, the dampening assembly 4 is provided with a dampening end, which engages with the gravure roller 2 in a concave-convex manner. This increases the contact area between the dampening end and the gravure roller and also prevents the cleaning liquid from splashing everywhere. Furthermore, the dampening assembly 4 is located slightly above and to the side of the gravure roller 2, and the arc-shaped surface of the dampening end engaging with the gravure roller 2 facilitates the removal liquid falling into the bottom trough 10.

[0025] like Figure 3 As shown, to ensure the continuity of the cleaning effect and increase the cleaning area, the cleaning component is detachably connected to the washing end. The extension direction of the cleaning component (not shown) is consistent with the axial direction of the gravure roller 2. The washing end is provided with a mounting groove 41 and a fixing hole (not marked). The cleaning component is not shown and is installed during use. The cleaning component is a metal blade and is fixed by a screw that mates with the fixing hole. The top of the screw is located inside the opening of the fixing hole.

[0026] To facilitate flexible replacement of the cleaning components, the end of the rinsing assembly 4 facing away from the liquid outlet 40 is a connecting end. The connecting end is rotatably connected to the coating head 3 via a rotating shaft 44. The rinsing assembly 4 includes a fixing member 43, which is used to fix the relative position of the rinsing assembly 4 and the coating head 3.

[0027] To further increase the wetting area and ensure more thorough removal of the dry liquid, the outlet 40 is elongated and its extension direction is aligned with the axial direction of the gravure roller 2. The outlet 40 can be located above or below the cleaning element. Preferably, the outlet 40 is located above the cleaning element. Regardless of whether the gravure roller 2 rotates counterclockwise or clockwise, the coating liquid delivered by the outlet 40 flows along the arc-shaped surface of the wetting end towards the cleaning element and wets the roller surface of the gravure roller 2. Figure 3 The display shows that the liquid outlet 40 is located below the cleaning component.

[0028] like Figure 2 As shown, the structure of the optimized fine-tuning component 5 includes a support roller shaft 50 and a telescopic component 51. The axial extension of the support roller shaft 50 is consistent with the axial extension of the gravure roller 2. The base 1 is provided with a guide (not labeled). On the lower surface of the support seat 501, there is a guide rail for the support seat 501 and the base 1 to fit together. The extension direction of the guide is perpendicular to the extension direction of the gravure roller 2. The two ends of the support roller shaft 50 reciprocate along the guide through the support seat 501. The base 1 is also provided with a limiting component 52, which is a bolt. The support seat 501 is provided with a through hole that fits with the limiting component 52. The limiting component 52 is inside the through hole and is used to fix the working position of the support roller shaft 50. The fixed end of the telescopic component 51 is fixedly connected to the base 1, and the telescopic end is fixedly connected to the support seat 501. The support roller shaft 50 is connected to the drive component 500, and the coating head 3 is fixedly connected to the support roller shaft 50. The drive unit 50 rotates the support roller shaft 50, causing the coating head 3 and the gravure roller 2 to be in an angled opening state, which facilitates the inspection of the interior of the coating head 3. The telescopic component 51 allows the coating head 3 to move closer to or further away from the gravure roller 2.

[0029] The fine-tuning component 5 also includes a first connector 53. One end of the first connector 53 is fixedly connected to the support roller shaft 50, and the other end is provided with at least two fixed through holes. The coating head 3 is provided with fixed connecting rods that cooperate with the fixed through holes one by one. One of the fixed connecting rods is threadedly connected to the coating head and the first connector.

[0030] The infusion tubing 6 includes a main outlet 600 and a bypass outlet 601. The main outlet 600 is connected to the coating head 3, and the bypass outlet 601 is connected to the inlet 42 of the rinsing assembly 4. The main outlet 600 and the bypass outlet 601 are respectively equipped with a first regulating valve (not labeled) and a second regulating valve (not labeled). The flow rate of the main outlet 600 and the bypass outlet 601 is adjusted by the first and second regulating valves, respectively, providing good adjustment flexibility. The second regulating valve is a one-way valve to prevent backflow of the cleaning fluid. The bypass outlet 601 is connected to the inlet 42 of the rinsing assembly 4 via a connecting conduit (not shown), and the main outlet 600 is connected to the coating head 3 via another connecting conduit (not shown).

[0031] like Figure 2As shown, when the coating head 3 changes its position via the fine-tuning component 5, in order to maintain the relative position between the infusion tube 6 and the coating head 3, and to maintain the connection status and position of the connecting conduit, the infusion tube 6 is connected to the support roller shaft 50 via a second connector 61. The second connector 61 is provided with a first connecting ring that sleeves on the support roller shaft 50, and a second connecting ring that sleeves on the infusion tube 6. The axial directions of both the first and second connecting rings are aligned with the axial direction of the support roller shaft 50. Furthermore, both the first and second connecting rings are movable rings, which can be flexibly removed and installed. The use of movable rings allows for flexible adjustment of the connection position between the infusion tube 6 and the support roller shaft 50, avoiding areas with dense distribution of connecting conduits, facilitating initial assembly and subsequent maintenance.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
